Résumé :
|
A mass balance method is described for calculating gas production from a surface or volume source in a small test plot from measurements of differences in the horizontal fluxes of the gas across upwind and downwind boundaries. It employs a square plot, 24m x 24m, with measurements of gas concentration at four heights (up to 3,5m) along each of the four boundaries.
